A：tim "by failing" modifies "engaging". i don't like it either, but again, the GMAT makes the rules.. :)
E: 'promise of keeping' is wrong. promise of + (real) noun or promise to do
摘：failure of 后面跟失败的对象，通常是名词，比如 the failure of the company，the failure of this slave rebellion，极少有跟动名词的情况，如果一定表示失败的具体行为，to do 是更好的选择；failure in 后面跟失败的所属的领域、范筹、活动等，比如failure in the exam, failure in the interview
